Im building a supercharged mini as well mate!
One question for you, your eaton m45, where did you get the inlet manifold from? Fabricated or did you modify an existing manifold?
Ive just realised thats the Midget charger kit from Moss Europe! Costs a fortune lol. Im making a manifold myself using an old mpi inlet manifold
Looks very niceshould suprise a few hot hatches at the traffic lights?
Once had a problem getting a Mini through the MOT with a fly-off handbrake I fitted.
